Given the production lead-times, I'm sure that sales have been double-counted on occasion - e.g. credit the sale in year X, and credit it again in year X+1 when the vehicle arrives. Sam exercised some poetic license with a few details in that article.

In our experience, as a dealer for 8+ years, production lead times have been the #1 sales inhibitor, putting aside a particular period of time when retail pricing became insane.
